.To all whom, it may concern:

tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. g

In Patent No. 733,67 4, granted to me July 14, 1903, I described an apparatus for cooling ozonizers, particularly characterized by a metallic electrode forming an indraft-chamher for the ozonized air and which is held between two dielectric surfaces coveredon the outside with a conductor.

The subject of the present application for a patent is an arrangement whereby the electrodes can be assembled in a manner very convenient for practical use.

The arrangement is represented in detail on the accompanying drawings, in which- Figure 1 is a front elevation of the entire apparatus. Fig. 1 is a front view, partly in section, taken on the line 1 1' of Fig. 2 Fig. 2 is-a transverse section. Figs. 3, 4, and 5 show in elevation three different forms of construction of the hollow metallic electrode.

The a paratus represented is especially intended or the production of ozone on a large scale, the suip'ply of the electrical energy being arrange [under special conditions to insure successful operation.

The elements are readily changeable and easily operated. They each consist of a metallic electrode a, forming an indraftchamber. These are laced between two glass dielectrics b c, eac of whch is covered First. The hollow central metallic elec-' trode may be provided with two side separating-strips 'i and a front strip 1*, Fig. 3. The indraft then takes place at the back, and the air enters through the holes 0.

Second. The front strip-may be omitted and the indraft-holes arranged along a middle line, as shown in Fig. 4.

Third. The hollow electrode maybe pro- 3 vided in its central portion with a set of orilices 0, as shown in Fig. 5, air being drawn in through a series of passages formed in the separating-strip all round the circumference.

The strips which serve to separate the plates of the hollow electrode should be 'made of glass or some other suitable insulating material. Each element rests on a flat plate m, provided with a ledge n at the under side. This forms a kind of drawer which rests on angle-irons p g in a slightly-inclined 'position. The drawers m n are provided with handles 7'.

The apparatus contains two series of pipes, the series 8 for the admission of the cold air and the seriest for the removal of the ozonized air. The glass doors y, have adouble partition h opening in either direction, as required, and adapted to render the apparatus air-tight. The electric current is supplied to the apparatus by two rigid cables 12 on, carefllly insulated. The connections between tie cable and the central metallic electrode may be effected by means of simple springcontacts Fig. 2; z connects the electrodes to one of the airpipes.

The apparatus in practice should include a cold-air generator. Liquid air, enriched by oxy en at a low temperature, gives very good resu ts. The use of pure oxygen is to be avoided, because the short-circuitin liable to take place in an atmosphere of suc gas is very dangerous. Inside the tube which forms the lnsulatin connection a small alu-' 5 An insulating connection minium vane may e placed to indicate the flow of air. Each of the joints which con-- v nect the insulating connection 2 to the airpipe is provided with a disconnectinfi stopcock Z, which will enable any one of file ele-1 ments of thebattery'to be removed and replaced without interrupting the working of the rest of the apparatus. 7

I claim- 1. In an apparatus for supporting and cooling the elements of statical ozonizers, the combination 'of the elements, a case, a series of ledges therein, plates supported by said ledges and provided with ledges at their lower extremities serving as supports for the elements, and electrical contacts adapted to be closed by the elements. 4

2. In an apparatus for supporting and cooling thevelements of static ozonizers, the combination with the elements, the case, a

series of ledges in said case and suitable terminals supported in said case, of plates supported by said ledges. and provided with ed es serving as supports for the elements, an electric spring-terminals carried by said elements and adapted to connect with the terminals in the case, when the elements are in position.

In witness whereof I have hereunto set my hand in presence of two witnesses.
